  1. 1. PREGNANCY<br />By: shenellD<br />7/4/2010<br />shenellD<br />
  2. 2. Pregnancy<br />Objectives:<br />What happens to an egg after fertiliZation?<br />How does a baby develop in the uterus?<br />7/4/2010<br />shenellD<br />
  3. 3. Fertilization <br /><ul><li>The union of ovum and spermatozoa.
  4. 4. Fertilization occurs in the outer third of the fallopian tube – the ampullar portion.
  5. 5. other terms are conception, impregnation, or fecundation.
  6. 6. The critical time span during which fertilization may occur is about 72 hours.</li></ul>7/4/2010<br />shenellD<br />
  7. 7. Steps in fertilization<br />7/4/2010<br />shenellD<br />
  8. 8. 1.Following ovulation, as the ovum is extruded from the graafian follicle, it is surrounded by a ring of mucopolysaccharide fluid (zonapellucida) and a circle of cells (corona radiata). These structures increase the bulk of the ovum, facilitating it’s migration to the uterus. <br />7/4/2010<br />shenellD<br />
  9. 9. 2. The ovum and surroundings cells are propelled, into the fallopian tube by the fimbriae, the fine, hair-like structures that line the openings of the fallopian tubes.<br />7/4/2010<br />shenellD<br />
  10. 10. 3. Only one ovum reaches maturity a month, a normal ejaculation of semen averages 2.5 ml of fluid containing 50 to 200 million spermatozoa per ml. or averages of 300-400 million per ejaculation. To promote the possibility of a sperm reaching the ovum, there is a reduction in the viscosity of cervical mucus at the time of ovulation.<br />7/4/2010<br />shenellD<br />
  11. 11. 4. Spermatozoa deposited in the vagina reaches the cervix of uterus within 90 seconds after deposition ant the outer end of the fallopian tube in 5 minutes. The functional life of spermatozoa is 48 hours.<br />7/4/2010<br />shenellD<br />
  12. 12. 5. Spermatozoa move by means of their flagella (tails) and uterine contraction through the cervix, the body of uterus toward the waiting ovum. All the spermatozoa that reaches the ovum cluster around the ovum’s protective layer of corona cells<br />7/4/2010<br />shenellD<br />
  13. 13. 6. Hyaluronidase(a proteolytic enzyme) is released by the spermatozoa which acts to dissolve the layer of cells protecting the ovum.<br />7/4/2010<br />shenellD<br />
  14. 14. 7. Only one spermatozoa is able to penetrate the cell membrane of the ovum. After it has done, cell membrane becomes impervious to other spermatozoa. <br />7/4/2010<br />shenellD<br />
  15. 15. 8. After penetration, the chromosomal material of the ovum and spermatozoa fuse and the structure is called zygote.<br />Sperm (23) + Egg (23) = Fertilized Cell (46)<br />7/4/2010<br />shenellD<br />
  16. 16. implantation<br /><ul><li>occurs on the seventh day after fertilization
  17. 17. Is the contact between the growing structure and the uterine endometrium</li></ul>7/4/2010<br />shenellD<br />
  18. 18. 1. Once of fertilization is complete, the zygote migrate for 3 to 4 days to reach the body of uterus. This time mitotic cell division or cleavage begins. The first cleavage occurs at about 24 hours<br />7/4/2010<br />shenellD<br />
  19. 19. 2. As the zygote reaches the uterus it consists of 16 to 50 cells. Its bumpy outward appearance is termed morula (from Latin word morus meaning “mulberry.”)<br />7/4/2010<br />shenellD<br />
  20. 20. 3. The morula continues to multiply as it floats free in the uterine cavity for 3 or 4 more days. Large cells tend to mass at the periphery of the ball, leaving a fluid space surrounding an inner cell mass. The structure is now termed blastocyst. <br />7/4/2010<br />shenellD<br />
  21. 21. 4. The cells in the outer ring are known as trophoblast cells. They are the part of the structure that forms the placenta and membrane the inner cell called erythroblast cells is the portion that forms the embryo.<br />7/4/2010<br />shenellD<br />
  22. 22. 5. After the 4th day of free floating, the residues of corona and zonapellucida are shed by growing structure. The blastocyst brushes against the rich uterine endometrium a process termed apposition. It attaches to the surface of the endometrium (termed adhesion) and settles down into soft folds (invasion)<br />7/4/2010<br />shenellD<br />
  23. 23. 6. The blastocyst is able to invade the endometrium because as the trophoblast cells on the outside of blastocyst touch the endometrium, they produce proteolytic enzymes that dissolve the tissue they touch. This allows the structure to burrow into endometrium, receive some basic nourishment of glycogen and mucoprotein and establishes an effective communication network with the blood system of the endometrium.<br />7/4/2010<br />shenellD<br />
  24. 24. stages<br />7/4/2010<br />shenellD<br />
  25. 25. Stage 1: Fertilization<br />1 day post-ovulation<br />1 Egg, 300 Million Sperm<br />0.1 - 0.15 mm<br />Fertilization begins when a sperm penetrates an an egg and it ends with the creation of the zygote. Fertilization takes about 24 hours.<br />7/4/2010<br />shenellD<br />
  26. 26. Stage 2: Division<br />1.5 - 3 days post-ovulation<br />First Cell Division<br />When cell division produces sixteen cells, the zygote becomes mulberry shaped. It leaves the fallopian tube and three to four days after fertilization<br />7/4/2010<br />shenellD<br />
  27. 27. Stage 3: Implantation Begins<br />0.1 - 0.2 mm<br />4 days post-ovulation<br />About four days after fertilization, the egg enters the uterine cavity.<br />Cell division continues, forming a cavity in the center of the egg. Cells flatten and compact on the inside of the cavity.<br />The entire structure is now called a blastocyst.<br />7/4/2010<br />shenellD<br />
  28. 28. Stage 4: Implantation Begins<br />0.1 - 0.2 mm<br />5 - 6 days post-ovulation<br />The blastocyst "hatches" around the sixth day<br />The implantation site becomes swollen with new capillaries, and blood circulation begins<br />7/4/2010<br />shenellD<br />
  29. 29. Stage 5: Implantation Completed<br />0.1 - 0.2 mm<br />7-12 days post-ovulation<br />The inner cell mass divides, rapidly forming a two-layered disc. The top layer of cells will become the embryo and amniotic cavity, while the lower cells become the yolk sac.<br />Placenta begins forming<br />7/4/2010<br />shenellD<br />

  163. 163. PELVIC FLOOR CONTRACTIONS (KEGEL’S EXCERISE)<br />Promotes perineal healing, increases sexual responsiveness and prevents stress, incontinence. While sitting at her desk or working around the house, the woman can tighten the muscles surrounding her vagina, relax tighten the muscles surrounding her rectum, relax, tighten her perineum, relax. It can be done 50-100 times daily <br />7/4/2010<br />shenellD<br />
  164. 164. ABDOMINAL MUSCLE CONTRACTIONS:<br />Help strengthen abdominal muscles during pregnancy and prevents constipation in the postpartal period. It can be done in a standing or lying position. The woman tightens her abdominal muscles, then relaxes and she can repeat the exercise as often as she wishes.<br />7/4/2010<br />shenellD<br />
